GRAlN-WEl'GHlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 342,261, dated May 18, 1886.

Application filed January 20, 1886. Serial No. 190,170. (No model.)

To all whom it may concern.-

Be it known that I, J OHN ADoLrHUs Mireil- ELL, aeitizen ol'the United States, and a resident of Vapella, in the county of De \Vitt and State of Illinois, have invented certain new and useful Improvements in GrainIVeighing Apparatus; and I do hereby declare that the fo1lowing is a full, clear, and exact description of the invention, which will enable others skilled in IO the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a perspective view of a portion 1 5 of a grain-elevator provided with my improved weighing apparatus. Fig. 2 is a front view of the apparatus. Fig. 3 is a vertical sectional View on line a; at, Fig. 4, and Fig. et is a vertical section on line g y, Fig. 2.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of weighing apparatus for grain-elevators and grain-chutcs in which the weight of the grain will tilt the bottom of a receptacle,which will tilt a guide, directing the ilow of grain to another similar receptacle; andit consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings,the letter A indicates the upper portion or discharge portion of a graiu-elevator, and 13 indicates the dischargechute of the same; and this ele- 5 vator and chute may be connected in any suitable manner to a thrashing-machine sepa rater, or be used for unloading grain from a vehiele or vessel, the elevator and chute -be ing in no manner material to the weighing apparatus, which may be secured to any elevator or discharge-chute. A casing, G, is suitably suspended under the dischargechute, and is formed with a semi-cylindrical bottom, D, having an aperture, E, at its lowermost point. A shaft, F, is journalcd in the front and rear sides of the casing, axially to the cylindrical bottom of the same, and at the lower end of a partition, G, and the forward endof this shaft is provided with an upwardly-projecting arm, II, having an adjustable weight or poise, I, sliding upon it and provided with a set-screw for adjusting it, and the arm is preferably graduated. Two wings, J J, are secured to the shaft, projecting at a right angle to each other from the shaft, and each wing 5 5 filling up the bottom of the compartment formed by the partition, and bearing with its outeredge against the cylindrical bottom ofthe compartment and with its side edges against the sides of the compartment, and the wings are secured at an angle of one hundred and thirtyfive degrees each to the upwardly-projecting scale-arm H. The upper end of the scale-arm is provided with two laterally-projecting arms or brackets, K K, projecting at right angles 6 from the upper end of the arm, and having their outer ends bent upward or inward to form shoulders or steps L. A guide-plate, M, is hinged with its lower edge to the upper end of the partition, swinging within the upper portion of the casing, and the upper edge of this swinging guideplate is provided with outwardly-projecting lugs N and 0, rest ing against the upper edges of the front and rear side of the casing, and having the forward lug, N, engaged by one of the stops upon the brackets. It will now be seen that as the swinging plate is tilted to one side or the other it will cover the greatest portion of the upper end of one of the compartments, and will guide So the grain emerging from the chute into the other compartment, and the bottom of this compartment will be closed by means of the wing,which will be tilted upward in the same by the scale-arm, which has the stop of the bracket at that side bearing against the lug of the swinging guide-plate. As, now, the grain fills the compartment up, the weight of the grain will force the wing down against the weight of the poise upon the scale-arm,which has been adj usted to be tilted at a certain weight in the compartment, and at last the weight of the grain will tilt the swinging wing straight downward, opening the lower end of that compartment and at the same time tilting the 5 scale-arm,so that the other stop will strike the lug of the swinging guide-plate and tilt it so as to cover the now opened compartment and to uncover the compartment which now has its bottom closed, and which is now ready to be filled. The grain, passing out through the bottom of the casing may either be filled in 5 bags or it may be emptied into a vehicle or vessel, and it will be seen that when the compartment has received the desired weight of a grain, it will be automatically emptied and the other compartment filled, 8:0. 10 A suitable counting or recording device may be connected to the apparatus in a way such as toadapt it to be operated by one of the lugs projecting from the guide-plate M, as said plate is moved from one position of rest to the other, or by the shaft F or the handle H, as the latter passes from its momentary vertical posit-ion to a position of rest.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States 1. In a grain-weighing apparatus, the combination of a casing having apartition, ashaft journaled to rock at the lower end of the partition and having wings closing the lower ends of the compartments and projecting from the shaft at a right angle to each other, a scalearm projecting upward from the end of the shaft and having a sliding adjustable poise and brackets projecting from its upper end provided with stops at their ends, and a guide-plate hinged to the upper end of the partition in the upper end of the casing and having a lug engaging the stops of the brackets, as and for the purpose shown and set forth.

2. In a grain-weighing apparatus, the combination of a casing having asemi-eylindrical bottom provided with an aperture at its lowermost point and having a partition extending from the axis of the semi-cylindrical bottom to near its upper end, a shaft journaled to rock at the lower end of the partition and having two wings projecting from it at a right angle to each other and closing the space between the curved bottom, and having a scale-arm proj ecting upward at equal angles to the two wings from one end of the shaft, a poise slid- -i ng adj ustably upon the said arm, brackets projecting at right angles from the upper end of the scale-arm and having stops at their ends, and a guide-plate hinged to the upper end of the partition and having lugs at the ends of its upper edge,having the forward lug engaging the stops of the brackets, as and for the purpose'shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
